Abstract

One of the challenges in the field of the incorporation of nanoparticles is how to control the core particle in the desired position/location of configurable shells. Herein, we describe a general and facile method for tuning the core position during the incorporation of gold nanoparticles (AuNPs) in different kinds of shells. The strategy involves the use of AuNPs with different sizes, shapes, and surface chemistry, and we investigated the intriguing “wetting” of solid shell domains on seed nanoparticles. The observable shell permits a simple qualitative measurement of the nanoparticle surface wettability. It creates a platform for the synthesis of anisotropic nanoparticles.
